The Schedule referred to in these Letters Patentand making part of the name.

To all whom it may concern Be it known that I, FREDERICK BucK, of the city, county. and State of New York, have invented a new and improved Process for Coloring Muslin, Paper, Sta;

. and I do hereby declare the following to he a full,

clear, and exact description thereof, which will enable those skilled in the art to make a-iid'use the same.

This invention consists. in mixing thewatencolors generally used for coloring paper, paper-hangings, 850.,

with soap or a saponilied product of oil, varnish, par-- afiine, orany saponifiable material, and after this mixture has been applied to the'i'abrio, treating the same with a solution of alum, in such a manner thata color is obtained which will resist the influence-of water, and which can'be used in many instances as asubstitute for oil-colors:

The. usual water-colors. used in coloring paper and,

other similar materials consist of auim al-. glue and chalk, with the desired pigment or coloring-material, and such colors are unable to resist the'iufluence of moisture.

I add to this usual coloring compound, common soap, or any sapouitied materiahsuch as saponified oil, varnish, or parafiine, and after all the ingredients have been thoroughly incorporated with each other, I apply the color to the paper, muslin, or other material to be colored, and then I draw said material, together with the coloring-compound, through alum or any other sulphate which will not change the color. By the action of the. alum or its equivalent, the glue and soap are rendered insoluble in water, and the color is rendered water-proof, or capable of withstanding the in fluence of moisture. I v

This process is of particular'value for paper-hang ings, and also for opaquiug windowshades, for which latter purpose, usually, oil-colors. are used, which are 'not only. more ekpensiveth'an my water-colors, but

also much more dilficult to apply.

' My water-color can be applied evenly and readily to a whole piece of muslin before cutting it up into shades, and the color, when applied, appears more uniform and even than the oil-color now used for that purpose. r v V In some cases-I have also used tannin, or materials containing such, as a substitute for alum.

What I claim as new, and desire to secure by Letters Patent, is-- paper, and other materials, by first coating them with a compound of glue, chalk, and soap, and then drawingtheiu through a solution of alum or other suitable agent, substantially as set forth.

2. Also, a water-proof coating for paper, muslin, and other materials, produced by first applying thereto a mixture of glue, chalk, and soap, and then drawing it through a solution of alum or other suitable suiphate, substantially as described.
